I looked at the manual onlinehttp://www.cushcraft.com/support/pdf/a3s.pdf
and it appears they made a poor conversion from inches to metric. Since inches are native to Cushcraft, those are more likely correct.
The part labeled "EE" is 46.5 inches long which converts to, as you discovered physically, 118.1cm, and not the 188.1cm they list in the manual.
